Not as easy as it looks, eh? Seems that CMI had the right idea after all, and even had an FPU plus a software toggle. PA's only have 8 chips and could access most ROMs at 14MHz. >Currently I am converting the board into a SMD version, which will be >published. > >Erwin van Breemen > >BTW To the designers: don't publish your board before it works 100%.

Seems to me that there is too much competition with resale PAs dropping in price, and ICD's being a hair more than new PAs. 14MHz 68Ks were a great thing 3 years ago, but with 020's and 030 prices dropping like flies it makes more sense to do a Lucas/Francis type accelerator for the 500 (IMHO). Speaking from my experience, the accelerated 68K market is d.e.a.d. -- +------+ William J.
